Title: Manufacture of sprue of vacuum casting mold
Inventor: FUKAI NOBUYUKI
IPC: B22C9/08
Filed: 1984-12-06
Abstract: PURPOSE:To prevent the intrusion of sand into a product part in the stage of casting in a vacuum casting mold which consists of silica sand for molding coated with a plastic film by forming the cavity for the sprue prior to charging of the silica sand in the stage of forming separately the cup and bar of the sprue. CONSTITUTION:The sprue bar 21 is formed integrally with the pattern 22 and after the film is formed, the sprue cup 21' enveloped by the film is lowered to be brought into tight contact with the bar 21. A heater 30 is contained in the cup 21' to melt-cut the tightly adhered film and at the same time to weld the films at the outside circumferential part to each other. A molding flask is set and the silica sand for molding is put into the flask and is molded, then the cup 21' is raised and a top surface film is put on. The inside of the flask is then sucked to a negative pressure. The sprue cavity is thus formed prior to putting of the silica sand for molding into the flask in the above-mentioned manner, by which the danger for the intrusion of the sand to the mating faces 20 of the film is eliminated and therefore the intrusion of the sand into the product part is obviated.

Abstract: PURPOSE: To melt a plastic film smoothly by a hot cutting edge and a receiving base in an up and down direction to enhance the fusing strength of the film by incorporating a heater into the receiving base made of heat transfer material. CONSTITUTION: A plastic film PF is held between a hot cutting edge 3 and a receiving base 8 obtained by tensely laying a Teflon(R) sheet 11, and the hot cutting edge 3 and the plastic film PF are pressed against a heat resisting rubber 10 of the receiving base 8 heated by a self-contained heater 9 through the Teflon (R) sheet 11. The plastic film PF is heated from above and below by the hot cutting edge 3 pressed and the receiving base 8 to be melted and fused uniformly in an up and down direction.

Title: Method for charging sintering raw material
Inventor: KAWAGUCHI KATSUNORI
IPC: F27B21/10
Filed: 1987-10-14
Abstract: PURPOSE:To enhance the effect of a grain size segregation effect and to improve the air permeability and combustion efficiency of sintering raw material layers by classifying the sintering raw materials successively via a slit chute at the time of obliquely gliding the sintering raw materials and supplying the same to a traveling pallet. CONSTITUTION:The sintering raw materials 1a dropped and supplied from a hopper via a feeder are obliquely glided on an approach chute 2. The slit chute 3 formed by tensing plural pieces of wire-shaped members 4 having the same diameter in the transverse direction is provided on the extension line of this chute 2 and is so formed that the spacings between the wire-shaped members increase gradually from the top end part 5 toward the bottom end part 6. The very fine-grained raw materials 1b of the obliquely gliding sintering raw materials 1a are, therefore, classified and dropped first. The fine-grained raw materials 1c are then classified and dropped successively as the raw materials glide to the bottom end 6 side. The coarse-grained raw materials 1d which do not pass the slit chute 3 fall from the bottom end 6. The sintering raw material layers 8 consisting of the lower layer part 8a of the coarse-grained raw materials 1d, the middle layer part 8b of the fine-grained raw materials 1c and the uppermost part 8c of the very fine-grained raw materials 1b are thereby formed on the traveling pallet 7.

Title: Min capacitor and manufacture thereof
Inventor: HOSOYA KENICHI
IPC: H01P1/00
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To provide an MIM capacitor simultaneously preventing thinning of a capacity insulating film at a lower layer electrode end and deterioration of dielectric breakdown strength caused by ion milling damage and manufacture thereof. SOLUTION: A photoresist 9 for forming an air bridge is added to an end part of a lower layer electrode 3 where an air bridge is formed and an intersection part of an upper layer electrode 6 so as to perform patterning along an end part of the upper electrode 6. Since this photoresist protects a capacity insulating film from ions of ion milling, an ion milling damage does not occur, and deterioration of dielectric breakdown strength can be prevented. Further, the use of the photoresist for forming the air bridge generates no increase of the number processes.

Abstract: PURPOSE:To improve the quality of picture of an observation image in a laser treatment by reducing or removing smear in the laser treatment. CONSTITUTION:A signal calculated with a mean calculation circuit 18 is cleared of a halation part H to extract a smear component exceeding a specified level, namely, of a high luminance with a high luminance part calculation circuit 21 and a slight correction, that is, a correction to expand the bottoms of a low level of amplification and extraction components is performed with a signal expansion circuit 22 and an LPF23. Moreover, the smear component is removed from an original image with a subtraction circuit 26.

In other words, this prevents malfunctioning caused by halation or others.
